Hello Ryan,

Suggest using the calculator spreadsheet that's in the product folder. Can also use WEBENCH. Calculator will show you AC response for component selection. WEBENCH is an online simulator. We also have models for PSPICE for TI to evaluate time domain performance.

Hope this helps.

David.

I have done all the steps you mentioned but need the Average model in SIMPLIS software to run AC analysis.

Hello Ryan,

Have you tried WEBENCH?

Thanks.

I fully knew about this feature of WEBENCH and used it before!
But for now, my control system has a complicated compensation circuit which is not possible to implement and use in WEBENCH or quick start excel file!
I have the SIMPLIS simulation file of other controllers but was wondering if I can get for LM5146 as well.

Hello Ryan,

Please see link below, Tim had already shared a model with you previously.

Thanks David,

Since it is a shared account, I lost the traceability for the request!
